SerialNb; 533537 3 Claims. ,(Cl. 256-10) The invention relates to a gate construction, and more particularly to electrified adjustable gates.

The primary object of the invention is to provide a gate through the medium of which the smaller-pigs of a, pen or other enclosure may be separated from the larger, whereby to permit the smaller pigs to be separately fed, the gate being mounted for vertical adjustment to provide therebeneath an entrance or exit for a pen or other enclosure of such height as to permit the passage of pigs of the selected size, and the gate being provided with means adapted to subject to an electric shock any pig of a larger size attempting to pass through the entrance or exit.

Another object of the invention is the provision of a gate of this character, wherein the same can b adjusted for the separation of the smaller pigs from the larger ones, accordingly to a selected determined size of the smaller pigs, the gate being of novel construction and is unique for the purposes intended thereof.

A further object of the invention is the provision of a gate of this character, wherein the larger pigs are kept from crowding the small ones, particularly from a feed trough or stall, and thereby relieving injury to the weakerpigs or small sized ones.

A still further object of the invention is the provision of a gate of this character, which is simple in construction, thoroughly reliable and efficient in operation, strong, durable, conveniently adjusted, readily and easily latched in adjusted position, and inexpensive to manufacture and in-,

stall.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, lllustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a fragmentary levation of a pigsty showing the gate constructed in accordance with the invention applied thereto.

Figure 2 is a vertical central sectional view thereof.

Figure 3 is a horizontal sectional view of the same.

Figure 4 is a detail sectional view showing one of the spur disks i side elevation.

Figure 5 is a sectional view on the line 5-5 of Figure 1.

- suitable manner.

Figure 6 is a sectional view on the line 6-6 of Figure 1, looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a portion of a pigsty having at the opening ID on opposite sides of the same vertical posts II, which are anchored to the step l2, the sill portion of the said opening it, in any These posts II slidably support a slatted gate l3, which at opposite side edges thereof is fitted with dove tail runners l4, these being slidably fitted in corresponding shaped vertical guideways or grooves I4 so that the gate l3 will be slidably' interfitted with the posts I I, as is clearly apparent from Figure 3 of the drawings, to be raised or lowered at selected distances from the sill area of the opening l0.

Mounted on the bottom slat of the gate is an outwardly bowed or archled rail l5 carrying spaced spurtoothed disks It, the spacing being had at H, and this rail I5 is journaled in insulator sleeves I8 fitted within eyebrackets 19, which are secured to the gate I3 at 2B. This rail I5 is vertically swingalble and is held in adjusted position by a suspension strap 2! centrally fitted thereto through the medium of sector shaped filler board 22 and adjustably engageable by the holes 23 therein with a keeper hook 24 on a cross slat 25 upon the gate l3 as is clearly shown in Figures 1, 2 and 3 of the drawings. This filler board 22 is bracketed at 26 to the railing l5 to be rigid therewith, so that both the railing and board effect a canopy to the opening l0, when the gate is in a raised position.

The railing I5 is electrified through a current supply circuit 21, including a fence charger 28, the electrical connection 29 being had with this circuit, while the latter is grounded at 30.

The gate I3 is held in raised position by stop pins 3| selectively engageable in holes 32-provided in the posts H for resting position upon these pinsat opposite sides of the opening l0, there being a bottom cross bar 33 on the gate. The pins 3| are hand removed and hand adjusted.

The railing I5 is suitably insulated from the board 22, and the electric shock through contact is had with the spur-toothed disk l6 associated with this railing.

In the use of the gate the railing I5 is set at the horizontal position, approximately at rightangles to the said gate and the latter is raised the required height to permit the smaller pigs to pass through the opening l0, and should the larger pigs make the attempt to go through the opening l0, these will make contact with the disks l6 whereupon they will receive an electric shock through such contact and in this way turn away from the opening Ill without attempting to pass through the latter. In this manner the smaller pigs will become separated from the larger ones for the feeding thereof.

The railing l5 can be swung upwardly against the gate [3 and in this position avoids any contact of the pigs therewith, thus being in an inefiective position, so that the gate may be used as any ordinary gate.

What is claimed is:

1. A gate of the kind described, comprising spaced vertical supports, a gate slidably fitting the supports for opening and closing the space therebetween, an electrified railing vertically swingabl upon the gate, means for suspending 20 the railing at an outward angle to the gate, and means for electrifying the railing.

2. A gate of the kind described, comprising spaced vertical supports, a gate slidably fitting the supports for opening and closing the space therebetween, an electriified railing vertically swinga'ble upon the gate, means for suspending the railing at an outward angle to the gate, means for electrifying the railing, and spur-toothed disks carried by the railing.

3. A gate of the kind described, comprising spaced vertical supports, a gate slidably fitting the supports for opening and closing the space therebetween, an electrified railing vertically swingable upon the gate, means for suspending the railing at an outward angle to the gate, means for electrifying the railing, spur-toothed disks carried by the railing, and means for latching the gate in a raised adjusted position.
